The tool executes queries without binding the authenticated principal to DatabaseContext, causing per-type and per-bucket ACL checks to silently no-op and allowing authenticated users to read data they are explicitly denied at the per-type level. Attackers can prompt the AI assistant to execute queries against restricted types or buckets to retrieve sensitive data that would be rejected through normal query endpoints.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-chrr-vr3p-crcc","tags":[]},{"url":"https://www.vulncheck.com/advisories/arcadedb-before-26.9.1-acl-bypass-via-query-database-tool","tags":[]}],"exploitRefs":[{"url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-chrr-vr3p-crcc","tags":[]}],"hasPoc":true,"ai":null}
